The term itself vascularization identical " blood supply”, but in medical practice means the formation of new blood vessels. This is also a consequence of the normal functioning of the mechanisms of regulation of local blood flow.
What functions does
Usually this update blood supply carried out depending on the needs of the organism itself, in particular, on the metabolic rate. It is the metabolism and vascularization closely related - new vessels appear faster in children and, accordingly, more slowly in the elderly.
Moreover, for processes blood supply the amount of oxygen also affects - if it is low, vascularization on the contrary, it intensifies. This dependence is well demonstrated on the example of premature babies. Usually they are placed in oxygen chambers, but this same fact stops the growth of retinal vessels and even causes degeneration. Moreover, after the return of the newborn to the normal environment from the oxygen tent, the vessels in the tissues of the eyeball sharply become larger. They even grow into the vitreous body of the eye, leading to blindness.
There are many factors that promote the growth of blood vessels, known as angiogenesis. The best studied in this regard are several - angiogenin, fibroblast growth factor and endothelial growth factor.
Vascularization also associated with the fact that it depends on the blood flow itself, but in fact its level indicates the need for blood supply the body tissues themselves.

The role of the thyroid gland
thyroid gland considered an organ of increased vascularization, it is fed by several arteries - two lower and two upper. In rare cases, the central unpaired artery also acts in this process. Besides, good blood supply guarantees normal operation thyroid gland and, consequently, the organism itself.
Thyroid by no means an important organ in our body. First of all, it is responsible for the production of thyroid hormones.
The most basic are thyroxine and triiodothyronine. They control many areas: the processes of nutrient metabolism, support for the cardiovascular system, the gastrointestinal tract. In addition, they even affect libido and psycho-emotional state.
Besides, thyroid produces calcitonin, which regulates the absorption and amount of calcium in the body.
The thyroid-stimulating hormone of the pituitary gland plays an auxiliary role for the organ. TSH takes part in the synthesis of the main bioactive substances thyroid gland.
Examinations for diseases
To check thyroid gland, usually resort to diagnostics, which includes:
- palpation - in this way I evaluate the density, uniformity and size of the organ;
- Ultrasound - such an examination already provides more detailed information. For example, one can already judge the degree vascularization along with parameters such as volume. By the way, it should be no more than 25 cubic meters. cm for men and no more than 18 cu. see in women;
- a blood test allows you to understand what level of hormones thyroid gland and is there any problem, need for appointment treatment.
Typically, increased vascularization can act as a symptom of diffuse toxic goiter. In addition, in itself, it worsens the general condition of the body. The fact is that due to the excessive appearance of new blood vessels, there is also an influx of hormones. thyroid gland. Accordingly, the amount of T4 and TSH is growing inexorably, the norm can be exceeded by two to three times. Thyroid switches to enhanced mode.
This state is called hypervascularization. The main reasons why it appears:
- rapid growth of the body, early puberty;
- transferred viral infection;
- somatic diseases;
- hypertrophy of the thyroid gland;
- postoperative intervention;
- long-term medical therapy;
- stress and nervous disorders;
- development of nodular goiter of the thyroid gland;
- malignant tumor.
In addition, the vessels in the human body during hypervascularization constantly narrowed, respectively, tense. They can only be relaxed by factors such as low blood oxygen levels, vasodilatory signals, and special drugs can also be used.
That is, the etiology can be very different, so you definitely need to contact an endocrinologist to determine the exact diagnosis.
You can get more information about diffuse goiter on this site.
Symptoms
Vascularization thyroid gland, although it has many manifestations, it is not always clear to the average person - sore throats, frequent colds, weight changes do not look somehow unusual.
Basically the symptoms hypervascularization such:
- constant subfebrile temperature;
- pain in muscles and joints;
- change in the appearance of hair and nails;
- frequent colds;
- swelling;
- weight instability;
- general malaise, which includes irritability, increased fatigue and drowsiness;
- pressure is either increased or decreased;
- disorders in the human reproductive system: women may not have menstruation, men are at risk of impotence.
All of the above only indicates that it is quite problematic to identify this disease on your own. In addition, people tend to ignore the signals that their own body sends, which subsequently leads to chronic conditions.
What to do with hypervascularization of the thyroid gland
Doctors as treatment use several methods:
- Based on medications or selected hormonal therapy;
- Surgical intervention.
They begin mainly with the selection of the necessary drugs. in mild form vascularization of the thyroid gland even simple potassium iodide can be dispensed with. Usually, you still need to follow a certain diet, which necessarily includes foods rich in iodine. In this way, treatment conduct courses with a mandatory break.
The surgical method is most often used in advanced cases when medicines do not work. Surgeons in this case remove most of the thyroid gland, and after the patient is supported by special hormonal therapy. Constant monitoring by an endocrinologist is also necessary, since the body will no longer be able to fully regulate its work.
Thus, the appearance of new blood vessels may not be as positive as it seems at first. The process of angiogenesis itself is certainly necessary, but both an excess and a deficiency greatly worsen a person's well-being. In addition, it will not immediately work to understand that it is connected just with the endocrine system. Even doctors need time to make a diagnosis. Usually, an ultrasound examination, a blood test, and palpation are performed.
The parenchyma of the thyroid gland for normal operation must be supplied with a sufficiently powerful blood flow.
Quite a lot of pathological disorders are associated with disorders of the circulatory system in this area, since each change in this part of the provision of the thyroid gland can be caused by various factors.
To understand the question of what hypervascularization of the thyroid gland is, it is necessary to comprehensively consider the work of the circulatory system in the endocrine organ.
In the physiological norm, the blood flow in the thyroid gland is provided by two pairs of arteries, while one pair belongs to the upper part of the thyroid gland, and the second to the lower one.
Each of them is divided in the tissues of the body into the smallest vessels, due to which the full distribution of blood flow is ensured.
The regulation of blood flow occurs in the human body by changing the quantitative and volumetric part of the vessels.
For reference!
In some people, the central azygous artery also participates in providing blood flow to the tissues of the thyroid gland. According to statistics, quite rarely - about 6 - 8%.
As the main and most studied, intrasystemic factors affecting the growth of blood vessels, it is possible to indicate the following:
- antiogenin;
- endothelial growth factor;
- fibroblast growth factor.
Each of these elements is produced by tissues with low blood supply and, by activating metabolic processes, can contribute to increased vascularization of the thyroid gland.
Physiological changes in blood flow are a variant of the norm, but one should take into account the factor that such processes can indicate various types of pathologies.
Depending on the main changes in such a phenomenon as the vascularization of the thyroid gland, it is possible to diagnose some pathological conditions.
Most often, these are certain types of tumor disorders, both benign in nature and prone to malignancy (malignancy).
Symptomatic indicators
The processes of changes in blood circulation in the thyroid gland can proceed without noticeable deviations from the norm.
However, the most obvious signs of such a state of the circulatory system as vascularization of the thyroid gland are the following changes:
- heterogeneity of the surface of the thyroid gland;
- an increase in the body in volume;
- blurring of the contours of the gland.
In general, changes may vary depending on individual characteristics and the presence of any systemic disorders.
In this case, the process of growth of new vascular connections in the thyroid gland may be accompanied by some symptoms:
- increased sweating;
- frequent colds;
- swelling of the limbs;
- instability of body weight;
- general weakness and drowsiness;
- hormonal disruptions;
- decreased libido.
In general, hypervascular changes in the thyroid gland can only indicate that there is some pathology, which, in turn, should be diagnosed.
The proliferation of the circulatory system in this endocrine organ should be considered as some kind of diagnostic sign, for example, chronic inflammatory disorders in the thyroid gland can sometimes be implicit, but there is vascularization of the organ, which indicates to the specialist the need for additional research.
Diagnosis
The greatest amount of primary information about the state of the thyroid gland can only be given palpation examination glands.
The procedure can be performed in various positions of the patient. In the process, the following nuances are assessed:
- dimensional changes;
- organ homogeneity;
- the presence of nodal pathologies;
- diffuse changes.
Each of these disorders can also indicate that the blood flow is increased due to hypervascularization, however, one should also take into account the factor that vascular proliferation is not always determined.
To identify such a change, specialists refer the patient to additional studies, the basis for which are complaints of certain symptomatic manifestations.
The main studies indicated for suspected disorders in the thyroid gland are as follows:
- ultrasound diagnostics;
- color Doppler mapping (CDC);
- scintigraphic study;
- analysis for thyroid hormones;
- MRI and MRI with contrast.
In the process of conducting basic research, if any changes in the blood supply of the endocrine organ are suspected, specialists receive the necessary data indicating specific disorders.
One of the main indicators of such changes as vascularization or hypervascularization is an increase in the echogenicity of the thyroid gland.
For reference!
Refers to ultrasound, due to the methodology of execution, giving a clear picture of the state of the blood vessels, indicating the direction of inflow and outflow of blood. In addition, it is possible to perform some quantitative measurements with CFM.
An increase in the blood supply to certain areas of the gland can directly indicate the presence of nodal changes.
In such cases, studies by means of color doppler become some determinant of signs of the type of disorder and may indicate the risks of malignancy of the present node.
Depending on the type of blood supply to the altered follicle, that is, perinodular or intranodular blood flow, one can speak of risk identification.
Nodes with an intranodular type of blood supply are those that are provided with internal blood flow, the rest should be referred to as perinodular.
Treatment
Diagnosis of a pathology such as thyroid vascularization should be carried out exclusively by an endocrinologist.
Accordingly, the treatment is also prescribed in the doctor's office.
Depending on the indications of increased blood supply and the results of additional tests and studies, various types and directions of influence on the problem can be prescribed.
In those situations when the thyroid gland is enlarged without secondary pathologies, that is, the presence of nodular formations and other associated with vascularization, does not require any serious intervention.
In this situation, the medical specialist prescribes iodine preparations ( active ingredient) and foods with a high content of it.
In the process of applying the technique, certain breaks are made, which may vary.
Pathologies associated with vascularization and hypervascularization (the occurrence of nodular neoplasms, etc.) require a different approach to the process.
The patient may be prescribed the following types of drugs:
- thyroid hormone analogs;
- Levothyroxine;
- Tireot.
However, it should be borne in mind that in the process of using hormonal drugs to stop the presented pathology of the endocrine organ, it is necessary to constantly undergo control studies.
This is due to the fact that drugs used to stabilize the hormonal background in the required direction should be constantly varied in terms of dosage, and many of them have a goiter effect.
This indicates the possibility of a negative reaction to treatment, which requires timely correction or preparation of surgical intervention.
The possibility of malignancy of the neoplasms present in the thyroid parenchyma should also be mentioned.
In this case, the specialist decides on the urgent surgical removal of problem areas of the gland and the appointment of a certain replacement therapy for the rehabilitation period.
Replacement therapy can also be used in a lifelong version, but this happens only with large losses of thyroid tissue or its complete excision.

Vascularization of the thyroid gland is a special growth related to the blood vessels. This phenomenon leads to the emergence of various kinds of somatic diseases. If from an anatomical point of view, the organ has the correct location, then it is surrounded by an artery and a vein. The upper elements are responsible for feeding the isthmus, and the lower elements are responsible for supplying a sufficient amount of blood.
Reasons for the formation of the phenomenon
There are several factors that lead to the formation of the disease. Harmful elements develop from the tissue, leading to an increase in metabolic processes. As a result, the dimensional parameters of this organ can significantly increase.
Increased vascularization means an acceleration of the moment, which leads to a significant increase in the number of thyroid hormones. Signs of hyperfunction are formed when the number of T4 and TSH increases significantly, and the normative indicator is exceeded by 2 or 3 times. As a result of such phenomena, the thyroid gland begins to conduct its activity actively.
Factors affecting the work of the body:
- Increased and excessively active development observed in the body, its rapid maturation.
- The presence of viral infections, accompanied by significant complications.
- The presence of diseases of a somatic nature, the formation of hypertrophy in the region of the organ.
- Doctor's intervention after surgery and violation of the main functions of the system.
- Long-term therapy with therapeutic agents, including hormonal drugs.
- The occurrence of severe stress conditions.
- Factors suggesting the development of nodular thyroid goiter.
- The presence of malignant tumors and other phenomena.
Decreased vascularization leads to the fact that the endocrine organ is considered to be weakened. In the course of this, the synthesis of hormones is reduced, which leads to a violation of metabolic reactions and the formation of somatic diseases.
Low blood supply can cause injuries and anomalies, as well as interventions after surgeries. Other causes are compression factors, atherosclerotic plaques, abscesses in the cervical region. If increased vascularization is observed, then replacement therapy with hormonal agents should be used. Usually it quickly eliminates the lack of hormones, in particular thyroxine, triiodothyronine, their quantity and content in the blood becomes normal. A reduced level of vascularization entails the same danger as an increased one.
Diagnostics
Usually it is carried out by means of ultrasound, the advantages of this method for the thyroid gland are: accessibility and a high rate of information content. The result can be obtained in a short time. The diagnosis is made on the basis of complaints from the patient.
Some statistics: If the terminology is translated literally from English, then it means "blood supply". The thyroid gland receives blood from the arteries, in 8% of cases an unpaired disease may occur. The lesion is observed quite rarely, more often accompanies women.
Symptoms
During the diagnostics, the specialist measures the length and width, as well as the thickness of the organ, while automatically calculating its volume. The normal value of the indicator for an adult man is 25 cm3, and for a woman it is 18 cm3. The structure of the organ is homogeneous, does not contain nodes and other formations. The diagnostic technique allows you to assess blood flow, as well as conduct high-quality measurements of the organ. If changes are observed in it, this often indicates the functional features of the gland.
If there is suspicion of vascularization, it is necessary to seek help from an endocrinologist, who, if necessary, will refer other specialists for examination. Timely treatment is a guarantee of a quick recovery.
The thyroid gland, like many other organs, is subject to various kinds of diseases that affect the functioning of the organ and negatively affect the state of health. One of these pathologies is vascularization, what is vascularization, we will try to tell in this article.
- What is vascularization and the reasons for its development
- Symptoms
- Diagnostics and therapeutic therapy
What is vascularization and the reasons for its development
The growth of additional blood vessels in the thyroid gland is called vascularization. As a rule, this condition leads to a slight increase in the organ, and if there are no additional formations, then the disease does not pose a serious danger. In addition to increased vascularization, a reduced one is also diagnosed, such a violation leads to a weakening of the function of the gland, metabolic disorders, and becomes the reason for the development of many somatic ailments. The cause of increased vascularization is most often the increased work of the organ, in which there is an increased production of hormones, which stimulates the growth of the circulatory ramification of the gland. In addition, the factors that influence the development of the disease include:
Also affect the appearance of the disease and various kinds of injuries, anomalies of blood vessels, tumors of the neck.
Symptoms
The most obvious sign of the disease is an increase in the gland, with an ultrasound examination, the heterogeneity of its structure and fuzzy boundaries are diagnosed. Vascularization also differs in the following symptoms:
Diagnostics and therapeutic therapy
Before deciding on treatment, a thorough examination of the thyroid gland using ultrasound is carried out.
The most accurate indicator of the disease is increased echogenicity, and a blood test is prescribed to more accurately investigate changes in blood flow. Therapy of this pathology includes two main methods - hormonal treatment and surgical intervention.
Normal and pathological thyroid vascularization
The term "vascularization of the thyroid gland" is used to describe the blood supply to this organ.
The phrase can be found in the results of dopplerography or radiography, in the medical history or in personal communication with an endocrinologist.
Vascularization can be normal, which means that the blood supply corresponds to the anatomical norm, or pathological, which means there are some deviations.
When diagnosing, it is important to understand what causes hypervascularization, because one of the reasons for the intensive blood supply to the thyroid gland is cancer.
What should be the vascularization?
Since thyroid hormones must enter the bloodstream instantly, the organ is entangled in a branched and powerful network of blood and lymphatic vessels.
For each person, this network has some individual characteristics, for example, in 5% of patients, the central unpaired artery is included in the network.
What are the characteristic features of the circulatory system of the thyroid gland in all people without exception:
- There are paired arteries called thyroid arteries. The bottom pair feeds the bottom of each lobe, and the top pair feeds the top. Capillaries approach each thyreon and bring oxygen, iodine, selenium and all other nutrients to the follicles, without which the organ cannot exist.
- The outflow of blood is carried out due to paired venous vessels. Veins do not have their own muscles, so the direction of blood flow is set using valves.
If a doctor shows interest in a particular issue, then this issue is essential for the diagnosis or treatment of thyroid diseases.
Why are endocrinologists concerned about thyroid hypervascularization?
In some cases, the thyroid gland receives increased blood supply, and this alarms the endocrinologist. What pathological causes can cause such a picture:
- Cancer tumor. Malignant cells increase their number extremely rapidly. Such active growth requires uninterrupted nutrition, and when the existing circulatory system begins to be insufficient, new vessels form. The process of formation of new capillaries and larger vessels is called "angiogenesis". Ultrasound helps to see if the tumor has an active blood supply. The study reveals that there is a halo around the neoplasm with altered echogenicity.
- Benign cyst or nodule. With the growth of toxic and euthyroid nodes, vascularization also increases. The treatment of these two pathologies will take place in different ways, but the ultrasound picture can be very similar, almost the same.
- Inflammatory process. As a rule, with thyroiditis, the blood supply increases exactly as long as the active phase of the disease lasts, and then returns to normal. With inflammation of the thyroid gland, in addition to increasing blood flow, the flow of lymph to the area of affected tissues increases significantly. This provokes swelling and an increase in the volume of the gland.
Contrary to the prejudice common among patients, ultrasound does not help to accurately determine the nature of the node and exclude cancer.
In order to find out the cause of increased vascularization, you will have to do a fine needle biopsy.
For more information on the patient's condition, the endocrinologist gives a referral to a biochemical blood test.
It is highly desirable to also pass text on specific cancer markers.
How is the therapy carried out?
With the help of TAB, it is possible to find out what is inside the node, and unambiguously rule out cancer. The procedure is extremely simple:
- Under ultrasound control, the endocrinologist pierces the node with a special aspiration needle. Local anesthesia is used to relieve pain.
- The needle sucks up a small amount of fluid or colloid contained in the knot.
- The sample is sent to the laboratory. After studying the cellular composition, the laboratory assistant issues a conclusion whether cancer cells are detected or not.
Further actions depend on this conclusion. If cancer is found, then the following should be done:
- Completely remove all malignant tissue. Monitor the patient's condition in dynamics in order to immediately stop a relapse if necessary. If there is no metastasis yet, then the prognosis for complete and final recovery is favorable in 85% of cases.
- If the cancer has spread to the cervical lymph nodes, they should also be removed. If the doctor believes that there is a real threat of metastasis, then for all types of cancer (except medullary), treatment with the isotope of iodine 131 is prescribed. According to indications, chemotherapy is performed.
Even a non-malignant node can pose a threat to health.
Active vascularization indicates a rapid growth of the neoplasm.
If the tumor is already more than 4 cm in diameter, then it must be removed surgically.
If the diameter is less than 4 cm, minimally invasive techniques can be used.
With the help of an injection of ethyl alcohol, it is possible to remove small nodes relatively painlessly and quickly.
Another popular method is laser surgery.
If the nodes do not interfere with the work of the thyroid follicular cells and do not interfere with the synthesis of hormones, then no further treatment is required.
And if the nodes have violated the hormonal background, then it is restored with medication.
Treatment will certainly lead to a successful result if the cause of the increase in vascularization is found out in a timely manner.
Is a hypoechoic thyroid nodule dangerous?
What can be echogenicity?
A hypoechoic thyroid mass is a fluid or nodular structure that is detected during an ultrasound examination. If we compare the hypoechoic node with healthy areas of the gland, then it will look much darker on the monitor screen. In most cases, endocrinologists refer the patient to an ultrasound of the thyroid gland if cancer is suspected.
If we look at the statistics, then out of 300 patients with hypoechoic thyroid, 200 were diagnosed with cancer. As a rule, an instrumental study will show a modified uneven structure of such areas. If these changes are detected at an early stage of neoplasm, then there is every chance to save human life and health.
The echogenicity of the thyroid gland can be:
- Reduced - hypoechogenicity;
- Normal - isoechogenicity;
- Increased - hyperechogenicity;
- Anaechogenicity - the absence of a signal in the study of structural changes in the thyroid tissue.
If during ultrasound the signal is isoechoic, then it does not change in any part of the organ, and this indicates that there are no diffuse changes in the thyroid gland, an increase in density. In other words, an isoechoic node indicates that the patient is absolutely healthy.
A hyperechoic signal can be caused by calcium salts formed on the tissues of the thyroid gland, due to a violation of the electrolyte-salt metabolism in the body. A hypoechoic node occurs as a result of structural changes in the tissues of the gland. Most often, this signal indicates the presence of a malignant formation of the thyroid gland.
Correct diagnosis
If, after ultrasound, the patient was given a conclusion about the presence of a hypoechoic node with a diameter of more than 1 cm, then this should be followed by a biopsy of this area. You will also need to take a blood test for tumor markers and hormones.
The absence of any pathological changes based on a blood test gives the doctor the right to observe expectant tactics. That is, for six months it will be necessary to monitor the patient's condition. To do this, the patient must monthly take blood tests for biochemical parameters and periodically do a biopsy under ultrasound.
A biopsy involves the penetration of a thin needle into the cavity of the neoplasm. Within a few seconds, the doctor takes a small piece of tissue for cytological examination. If tissue analysis under a microscope showed that thyroid cells begin to degenerate into a malignant formation, then the patient is diagnosed with oncology.
Possible diseases
If the echogenicity of the gland is reduced, then this may indicate an iodine deficiency in the body, autoimmune thyroiditis, or the presence of diffuse toxic goiter. In this case, the patient is prescribed a blood test to determine the level of thyroid-stimulating hormone.
Echogenicity is increased in those patients who live in a zone of increased radiation, and where poor ecology is noted.
Chemical poisoning with toxic substances also gives impetus to a diffuse change in the thyroid gland. The hereditary predisposition to the formation of a hypoechoic structure in the gland is not denied.
Thyroid nodules are formed as a result of:
- Inflammatory process that provokes the growth of a cyst;
- Endemic, colloid goiter;
- The occurrence of adenomas of the gland;
- The appearance of tumor neoplasms, both benign and malignant;
- Iodine deficiency in the body;
- Radiation or chemotherapy.
Symptoms of the disease
The nodes of the gland make themselves felt long before the instrumental analysis. If the node is more than 3 cm, then the patient may have complaints of difficulty in swallowing, complete or partial loss of voice, increased sweating, and fever for a long time.
A person also has tachycardia, shortness of breath, exophthalmos (protrusion of the eyeballs), delayed blinking of the eyelids, due to a violation of the autonomic system of the eyes.
The skin begins to rapidly lose elasticity, becomes extremely thin and soft. On the part of the digestive tract, the patient has bloating, constant constipation, the presence of a gag reflex after each meal, and nausea.
If the patient is constantly thirsty, then this may be a signal of a violation of water metabolism in the body. When lifting weights or after ordinary climbing stairs, the patient has weakness in the muscles, pain in the joints. Thyroid nodules in women lead to menstrual irregularities, cessation of ovulation, and even infertility.
Treatment of thyroid diseases
Any treatment must begin with a correct diagnosis, so you need to get a doctor's opinion. As mentioned above, if the patient experiences discomfort in the thyroid gland, it is necessary to undergo a physiological examination by an endocrinologist. Then an ultrasound diagnosis should be made, which will show if the patient has a hypoechoic node.
A blood test for hormones and tumor markers can confirm or refute the diagnosis. After the examination, the endocrinologist prescribes medication or the elimination of the hypoechoic structure by the surgical method.
For the treatment of colloid goiter, the drug L-thyroxine is used. It aims to stop cell division of the node. Thyrostatic drugs - espa-carb, thiamazole, propicil can reduce the diffuse size of the nodes. If the thyroid nodules were formed as a result of iodine deficiency, then in this case medicines iodide 200 and potassium iodide 200 are indicated.
Surgical intervention for a hypoechoic formation is necessary if it exceeds 3 cm in diameter or is malignant. To avoid malignant changes in the thyroid gland, it is necessary to undergo a preventive examination by an endocrinologist every six months.
